As expected, Facebook today launched its App Center, which is said to to make it easier to find apps users can enjoy with friends. The App Center gives Facebook users personalized recommendations and lets them browse the apps their friends use. According to Facebook, it only lists high-quality apps, based on feedback from people who use the app, and therefore it's more a kind of recommendation engine than a real stand-alone app store, especially because the apps are downloaded after from Google's Play Market or iTunes. The App Center is available in the Facebook iOS and Android apps, as well as on Facebook.com and features mobile and web apps, such as Pinterest and Nike+ GPS.

Discovered apps found on the computer can also be send to a mobile device using the new "Send to Mobile" feature. Every app in the App Center has screenshots and a detailed description, so users can learn more about it before installing it. It helps to control privacy by showing the information an app needs and letting users choose who can see the activity on Facebook.

The App Center will begin rolling out to people in the U.S. today, with more than 600 apps. It will be available to everyone in the coming weeks.
